Take your telescope anywhere with this portable rechargeable power supply. The extra large Power Tank 17 is also useful as an emergency roadside accessory. It includes an emergency light, siren, am/fm radio and booster terminals in to start weak car batteries.

Finderscopes are secondary scopes, used to help locate objects in the main telescope. The larger the finderscope, the more you'll see, to an upper limit of 50mm. Units larger than 50mm have too narrow a field of view to be useful. Finderscopes mount onto the main telescope tube and are an invaluable tool in locating objects for viewing.

Finding objects couldn't be easier! A 1x, or unit power finderscope designed so you can point the telescope while scanning the sky with both eyes. A mirror lens projects the image of a LED illuminated pinpoint into the line of sight, providing you with a red dot of light to center on the object you want to view.

The 6mm high power 1 1/4" E-Lux eyepiece is a 4-element Plössl with features that maximize it's performance at a very economical price.

Features of this series include fully coated lenses (every air to glass surface is coated with anti-reflective coatings), eyepiece cups to reduce stray light, and each model is threaded for use with eyepiece filters.

The 6mm high power Omni eyepiece is a 4 -element premium symmetrical Plossl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

The 20mm medium power Omni eyepiece is a 4 -element premium symmetrical Plössl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

The 25mm medium power Omni eyepiece is a 4 -element premium symmetrical Plössl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

The 32mm low power Omni eyepiece is a 4 -element premium symmetrical Plössl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

The 40mm low power Omni eyepiece is a 4 -element premium symmetrical Plossl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

The Omni Barlow is a high quality 2x Barlow lens that doubles the magnification of all 1.25in. eyepieces. This economically priced Barlow has great features like, low profile, 2-element fully-multicoated optical design and blacked lens edges. Barlow lenses provide an economical and also easy way to increase the magnification range of your eyepieces. A Barlow lens doubles the magnifying power of your eyepiece by doubling its effective focal length that it is used with. For example, using an 18mm eyepiece used with a 2x Barlow lens, this would have the magnifying power of a 9mm eyepiece. The results of a Barlow lens is like having two eyepieces in one. Barlow lenses are an affordable way to achieve high-power viewing of the moon and planets as well as other celestial objects. The lenses can be mounted into either your telescope focuser or visual back.
